stratified, random statistical survey design. Sampling within these watersheds began in 2004 and is ongoing in selected watersheds. There are an additional 25 sites where monitoring began in 2010 to refine the approach for identifying vulnerable watersheds. EPA is evaluating the results of the atrazine monitoring program, also in part, to identify the characteristics of those watersheds that resulted in atrazine exposures exceeding the Agency’s LOC and to extrapolate those results to other non-monitored locations to determine where atrazine concentrations may exceed the LOC.

In December 2007, EPA presented to the SAP the use of the Comprehensive Aquatic Systems Model (CASM) as a tool to determine an LOC that relates time variable monitoring data to effects identified in a series of microcosm and mesocosm studies. The SAP recommended that EPA:

1. Work with the CASM–Atrazine model to make the population time series more realistic;

2. Provide a better validation of this model, and

3. Conduct a more comprehensive sensitivity analysis.

In May 2009, EPA presented a simpler alternative to the CASM-based approach to relate surface water monitoring data to the microcosm and mesocosm data, called the PATI. Other issues presented at this meeting included a revised assessment of the microcosm and mesocosm exposure profiles, an update on the ecological monitoring program results, interpretation of the monitoring results with PATI, identification of the watershed factors driving atrazine runoff, and extrapolation of those results to the entire atrazine use area to identify other areas where atrazine exposures may exceed the LOC. The 2009 Panel suggested that both the CASM–Atrazine model (presented by Syngenta) and PATI were suitable assessment tools for atrazine. The PATI model was recommended by the SAP as a generic assessment tool for developing an LOC, while CASM wasrecommended by the SAP as a sitespecific assessment tool because of the need for extensive site-specific data. The Panel noted that a limitation in the CASM model is the lack of understanding of the sensitivity of model predictions with correlations among model parameters. The SAP recommended that EPA re-evaluate the meso/microcosm data set for study quality and concentration-specific effects, and provided additional citations for meso/microcosm studies to consider including in the assessment. They also recommended using a probabilistic approach to determine the LOC. The SAP concurred with EPA’s incorporation of depth to impervious layer and slope to identify vulnerable watersheds for atrazine runoff as part of the atrazine vulnerability index. They also cautioned EPA that several watershed factors such as atrazine use intensity and rainfall are temporally dependent and, therefore, should not be considered minimum criteria in the vulnerability index.
